Abstract:
Sentinel lymph node (SLN) detection in endometrial cancer is still in the exploration stage. But a good many studies have confirmed the feasibility of SLN detection in patients with early endometrial cancer. Higher detection rate of SLN can be achieved by the combination of blue dye and radiocolloid. Compared with intracervical injection, more injections at different sites of the uterine corpus and hysteroscopic injection may improve SLN detection rate and para-aortic SLN detection rate. SLN detection rates are also related to some other factors such as the amount of tracers, the interval between injection and detection, and the depth of myometrium invasion. Serial-step section of SLN combined with immunohistochemistry staining with anti-cyto-keratin may improve the detection of micrometastasis (MM) in SLN. SLN procedure can detect MM which cannot be found by traditional pathological techniques. The ultrastaging will allow better stratification of patients at intermediate risk and can provide valuable informaiton for the selection of adjuvant therapy, thus decreasing the recurrent rate.
